EXCELLENT!

I have said this, however somewhat less eloquently. Mike DiTolla is
employed by Glidewell Labs as their dentist/representative.

He knows what he is talking about.

Since I barely knew how to prep a crown, let alone a veneer, I was
hoping to do this as a no-prep veneer case, but it wasn't meant to be.
My instructor pointed out that there is really no such thing as a
no-prep restoration in dentistry. His biggest issue was with the
margins, particularly the gingival margins. Without any reduction done
for the gingival margin, it was inevitable that there would be poor
contour in that area of the restoration, and due to its bulbous
nature, it would become a plaque trap that would ultimately lead to
gingival inflammation and discoloration. He pointed out that even when
proper reduction was done, if the emergence profile was incorrect and
too bulky, the same negative effects would occur to the gingiva. The
goal in restorative dentistry is to mimic Mother Nature with proper
dimensions and contours. If a tooth is left a little bulky in the
middle or incisal third it may or may not be problematic from an
aesthetic standpoint, but not from a health standpoint. However, if a
tooth is left bulky in the gingival third, the ramifications are much
more serious, since they are occurring at the perio-prosthetic
interface.
